Our original ideas were inspired by some illusions that make one participant believe that the other participant is them.  We came up with our own version of an illusion similar to this.  We were most interested in the design of our illusion and how it was going to work.  We first created a box with a wall in the middle separating the two participants hands.  Then, we cut out mirrors to go in the corners of the box.  The main part of our illusion was the LED strips in the center of both sides of the box.

This illusion requires two participants; one person will put their hand in the left side of the box and the other will put their hand in the right side of the box.  Each person hovers over the LED strips with their hand.  Both participants will look in the mirror right in front of their hand and look at the other person’s hand.  When the LED lights up, you both touch the light and when it disappears you remove your finger from the LED strip.  This illusion works because both of the participants are doing the same movements.  

The Hand-swap Box is an illusion box is designed to trick two participants into seeing and believing that the other’s hand is their own.  In our ilusion,  the two participants are following and tapping the LED lights when they light up.  They are doing this at the same time that they are looking at the other person's hand in the mirror.  You may ask yourself, how does this illusion actually work?  The illusion only works well when there is time between "rest time" (when your finger is hovering over the LED strip) and "moving time" (when you move your finger onto the LED strip).  This gives the brain enough time to process the movement that is going on.  Once enough time has passed, you will start to believe that they other hand is your.
